English translation of German description:The Keithley Model 193A is a fast System DMM.
At 6˝ digit resolution, the LED display can display ±2,200,000 counts.
The range of this analogue-to-digital (A/D) converter is greater than the normal ±1,999,999 count A/D converter used in many 6˝ digit DMMs.
The built-in IEEE-488 interface makes the instrument fully programmable over the IEEE-488 bus.

DC voltage measurements from 100 nV to 1000 V.

Resistance measurements from 100 ľohms to 200 Mohms.

RTD temperature measurements from -100°C to 630°C (only with suitable sensor, not supplied).

Please ask for the additional fee for a current and traceable ISO calibration.
